Advance Information

Message Type Description

RTCM 1230 GLONASS code-phase biases

Table 6: Supported output RTCM 3.3 messages

1.5 Broadcast navigation data and satellite signal

measurements

The ZED-F9P high precision receiver can output all the GNSS broadcast data upon reception

from tracked satellites. This includes all the supported GNSS signals plus the augmentation

service QZSS. The UBX-RXM-SFRBX message is used for this information. The receiver also makes

available the tracked satellite signal information, i.e. raw code phase and Doppler measurements,

in a form aligned to the Radio Resource LCS Protocol (RRLP) [3]. For specification of the protocols

see the u-blox ZED-F9P Interface Description [2]

1.5.1 Carrier-phase measurements

The ZED-F9P modules provide raw carrier phase data for all supported signals. This is along with

pseudorange, Doppler and measurement quality information. The data contained in the UBX-RXM-

RAWX message follows the conventions of a multi-GNSS RINEX 3 observation file.

Raw measurement data are available once the receiver has established data bit

synchronization and time-of-week. For specification of the protocols, see the u-blox ZED-F9P

Interface Description [2].
